made of metal instead of a clay product.

By the construction and arrangement herein described, it will be seenthat the blocks cannot be drawn apart as long as the tie-plates andtransverse walls of the blocks remain intact. Neither can one `tier ofblocks be drawn endwise or in anyway out of line on another'. Thearrangement of the tieplates makes a good wide, close, ldurable mortarjoint between every tier of blocks having single openings, and at everyother tier when blocks with three openings are used. Also, thetransverse end walls B being mortared all over will form durable mortarjoints between each of the blocks thus insuring good solid mortar jointsall around the blocks the full thickness of 4the wall, and at the sametime forming an isolated dead air space in each and every block. Y

lVhen blocks having horizontally disposed openings are used there isalways trouble in getting the ends of the blocks sufliciently mortaredto make a good durable joint. The abutting ends of the blocks withhorizontally disposed openings are seldom over threequarters of an inchthick, and sometimes not over half an inch thick 4and when used forbuilding silos, Jthe silage acid on the inside and the freezing Iandthawing on Ithe outside will in time cut through these thin oints ofmortar and make openings in the wall which will spoil the silage orren'der a building cold. By my invention this defect is overcome and astrong durable wall is provduced 'having large isolated dead air spacesthroughout which will effectuallj7 keep out frost and cold in vanyordinary climate. The tie-plates will hold ythe blocks together at bothtop and bottom instead 'of f Y one side only. When clips are 'used whichcatch over the upper edges only, the blocks will not be held together atboth sides. The ties are also economical in holding the mortar andpreventing it from dropping into the openings and being wasted. In casethe ties should be a little` too narrow to elffectu'- ally close theopenings, a strip of metal lath may be laid on the open side or othermeans may be used to catch and hold the mortar and form a vsolid mortarjoint.

j The entire arrangement is extremely simple and easily laid, and iseffective in every respect both in holding the blocks securely togetherand in forming isolated dead air spaces throughout the wall. Also theconstruction is such that ordinary variations in the size and shape ofthe blocks and ties, caused by shrinkage and warping in burning is amplyprovided for, which cannot be successfully done when the ties havenotches in both their upper and lower faces.

Furthermore, thetie-plates may be made of uniform thickness, whichl isan important feature that cannot be had when there are notches in theirfaces and they do notjhave to be made wider on their outer than on theirinner sides when used in a curved Wall.

that I claim is:

l.. In a-wall, the vcombination of a series of hollow building blocksplaced in a row.,

each having Ia vertically disposed opening and transverse walls, aseries of tie-plates, each having a depressed center correspond'- i-ngapproximately to and entering the upper edge of the opening in the blockbelow it and having upwardly `offset ends resting 'on the transversewalls of the block, and another series of hollow blocks lsimilar to therst laid upon lthe first series so as to break joints, and the loweredges of the adjacent transverse walls of said blocks inserted in thedepressed portion between the upwardly offset ends ofthe tie-plateimmediately below said transverse walls.

2. Ina hollow wall, the `combination 0f a series of superposed blockshaving vertical openings and abutting transverse walls, a series oftieplates each having a rvdepressed center, 'corresponding to and'entering the upper edge of `the opening ina block, and upwardly offsetends resting upon the ktransverse walls of the block, the upwardlyoffset ends of the adjoining tieplates being bound together by entering'the lower edge of the vertical openings of the blocks above and beingheld by the transverse walls of said blocks. l l

'3. In a wall, a plurality of superposed series 'of hollow buildingblocks, o en at their upper and lower ends and aving transverse walls,in combination with a plu ralfity of series 0f interposed tie-plates,each provided with a depressed portion and upwardly offset ends, thesaid depressed portion corresponding to and ente-ring the opening in theupper end of an adjacent block, the upwardly offset lends resting uponthe transverse walls thereof, and the lower edges of the transversewalls fitting loosely in the depressed portions "of the tie-plates inthe next lower series 'of blocks and plates.

4;; A plurality of superposed series of hollow building blocks, havingvertical openings and abutting transverse walls, in eom-` blnatlon withe plurality of series of 1I1ter posed tie-plates each provided with ades pressed portion and upwardly offset ends, the depressed portions ofthe tie-plates eorresponding to and entering the openings in the blocksbelow, the upwardly ofset ends resting upon the Jnransverse wallsthereof,

and the lower edges of the adjacent transf.` l0

Verse walls of the blocks fitting loosely in thedepressed portions ofthe tie-platesntlie next lower series.
